Haiku is the app that runs on your phone, it only sends commands and will show status of the OP2. It also receives push notifications from HH.
HaikuHelper runs on the mac, and maintains a constant connection to your OP2. It stores its JavaScript code locally, and the engine that processes that is also run locally. NOTHING is written to the panel from either of these.
So, if you have a mac power failure, you will lose push notifications, as well as the advanced scripting you have done inside HaikuHelper. Any scripts written inside PC Access and stored on the controller will continue to run as long as your battery holds out.
The scripts and programming can work together with flag changes, button presses, etc. HaikuHelper monitors the entire system and can react to changes to pretty much any aspect of the system.
A good example is how I arm my house away each morning. I press a button on a UPB controller that is marked "Away Max" (Max is the dog) This fires off a program on the OP2 that (1) bypasses all of the motion sensors since the dog is home, (2) arms the alarm away, (3) sets the appropriate UPB scene to turn off or on lighting, and (4) presses a button called "Away Max". HaikuHelper picks up on the button press, and powers off all of my Logitech Squeezeboxes, and begins a temperature setback program.
If the Mac dies, the alarm will still arm, the zones will still bypass, etc. But I lose the more advanced stuff like the audio shutdown and temperature setbacks.
Hope that kind of clears it up.....
